The role of transrectal fine needle aspiration cytology in the diagnosis of prostatic nodules suspicious of malignancy--a study of 126 cases

Abstract

Transrectal fine needle aspiration cytology by Franzen technique was carried out in 126 patients having enlarged prostate which were suspicious of malignancy by clinical per rectal examination. Analysis showed benign adenoleiomyomatous hyperplasia in 40 cases, chronic prostatitis in 4 cases, tuberculosis of prostate in 4 cases, malignancy in 76 cases and 2 cases were reported as suspicious of malignancy. Comparison of aspiration cytology with histopathology, serial serum acid phosphatase estimation, repeat a spiration cytology after hormone therapy with or without orchiectomy and clinical follow up showed accuracy of cytologic diagnosis of 98.4 per cent. False negative was 1.6 per cent. There was no false positive diagnosis. No complication was encountered in this procedure.
